If you’re considering a career in commercial driving, now is the best time to start the licensing process and get your CDL (Commercial Driver’s License). This certification opens up career paths in various industries. You may drive dump trucks, school buses, tankers, or even combination vehicles, such as semi-trucks. The official Commercial Motor Vehicle Drivers Handbook (Texas CDL Handbook 2026) discusses commercial driving theory in detail. You should read its contents multiple times during your learning phase, focusing especially on the sections most relevant to your chosen profession.

The official General Knowledge Exam will evaluate your understanding of this subject through 50 multiple-choice questions. You must score 80% or higher to pass. We’ll help you achieve a passing score on your first attempt, but you must dedicate the following weeks to your learning phase. Our Texas CDL General Knowledge Practice Tests, when used regularly, can significantly boost your learning potential. You’re about to take the third practice test in this series, which includes questions similar to those you will get at the DMV office.

Customize your testing experience with the test settings menu located in the top-right corner of the page.
